Last night Gaia Repossi brought her sparkling touch to Tinseltown to celebrate her jewelry house’s arrival at Saks Fifth Avenue in Beverly Hills. Taking in the dinner at hot boîte Madeo were an equally dazzling crew including mega stylists Karla Welch and Petra Flannery, fashionable philanthropists China Chow and Elisa Sednaoui, and countless others. As guests checked out the wares, they lingered over bites and cocktails long into the evening.
